Bent normals problem

I use bent normals and on a skeletal mesh, and it looks very good. But there is a serious problem on the texture seams. Look at the pics attached.

Pic 1 is with BN enabled, you can clearly see the problem
Pic 2 is with BN disabled, no problems
Pic 3 is the BN texture as color
Pic 4 is the UV

Bent normals created in XNormal

Does anybody knows how to solve that?
